Abstract
The invention relates to a hot metal pretreatment desulfuration spray gun which comprises a steel structure and a plurality of preformed units, wherein the preformed units are sleeved on the steel structure end to end; Z-shaped right angles are formed in the seam crossings of the adjacent preformed units; the adjacent preformed units are sealed through being coated with refractory coating. The desulfuration spray gun provided by the invention can improve the thermal shock resistance of the fire-proof material, reduce the happening of crack, prevent the continuous expanding of the crack, and greatly improve the use quality; the fire-proof preformed units can be repeatedly used; not only the cost is reduced, but also a series of problems such as the breaking by a worker are reduced.
Description
Technical field
The invention belongs to field of metallurgy, be specifically related to carry out to molten iron the prefabricated component formula assembling desulphurization spray gun that stove processes outward.
Background technology
At present, in the Hot Metal Pretreatment of metallurgy industry, major part adopts Ukraine's vaporizing chamber type desulphurization spray gun, and it is the steel construction rifle core that will have welded, integrated poured shaping with mullite silicon carbide refractory castable, but there is following defect in traditional desulphurization spray gun:
1) desulphurization spray gun forms by refractory castable is integrated poured usually, although improvement can be carried out to offset between metal and refractory materials coefficient of expansion mismatch problem in thermal shock process on design of material, but this disadvantage cannot thoroughly overcome, more or less there is stress relief and the crackle produced, have a strong impact on the functional quality of desulphurization spray gun;
2) desulphurization spray gun adopts vertical integrated poured usually, due to spray gun longer dimension (4-5m), and wall thickness thinner (80-120mm), even so vibrating head and vibrating motor ancillary vibration are all difficult to the quality controlling to make, product stability is poor;
3) in traditional sense, desulphurization spray gun is integrated poured, and after rolling off the production line, refractory materials sinters through using, and cannot reuse after orcible entry;
4) integrated poured desulphurization spray gun is removed with pneumatic pick after using, and because rifle body refractory materials is inherently very firm, refractory materials sinters after using in addition, deals with suitable effort, not only takes muscle power but also affect environment.
Summary of the invention
The object of the invention is to the difficult problem overcome in technical field of refractory materials, a kind of brand-new desulphurization spray gun is provided to make theory, desulphurization spray gun steel construction stress rupture of causing different from refractory expansion coefficient in extremely cold very hot process can be improved, effectively can prevent generation and the expansion of crackle.
The present invention in order to achieve the above object, is on the basis of original shape at Ukraine's vaporizing chamber type desulphurization spray gun, eliminates steel construction and the integrated poured shaping mode of refractory materials, devises a kind of prefabricated component formula assembling desulphurization spray gun.
Prefabricated component formula assembling desulphurization spray gun provided by the invention comprises steel construction and some prefabricated components, and described prefabricated component is end to end to be sleeved on described steel construction.
Preferably, described steel construction covers insulating refractory fiber.
Preferably, the seam crossing of adjacent prefabricated component is provided with the right angle of zigzag, and adjacent prefabricated component is by smearing refractory paint sealing.
Refractory materials integrated poured for desulphurization spray gun lining system is made several independently prefabricated components, and prevent infiltration of molten steel by zigzag right-angle design, the seam crossing between prefabricated component is applied to refractory paint, then on the spray gun steel construction assembled, and regulating spring pressure mechanism compresses prefabricated component and is assembled into an entirety use.
Preferably, described prefabricated component adopts corundum porzite flame-proof raw material or flint clay High-Alumina refractory raw material.
Preferably, described prefabricated component wall thickness is 80-120mm, is highly 250-350mm.
Preferably, the different fire-resistant prefabricated member at position that uses is made up of the refractory materials of unlike material.Preferably, the prefabricated component that the position (as the position such as hydraucone, slag line) that work area environment is comparatively severe adopts the good refractory materials of fire performance to make.
Preferably, described prefabricated component seam crossing profile adopts the anti-molten steel infiltration design of zigzag, and scribbles refractory paint encapsulation process.
Preferably, described spray gun is provided with pressure mechanism and is compressed by prefabricated component.
Preferably, described pressure mechanism is spring application mechanism.
After certain fire-resistant prefabricated member is subject to Eroded, after cooling of rolling off the production line, opens spring pressure structure, directly can change this block prefabricated component, and can again come into operation.
Prefabricated component formula of the present invention assembling desulphurization spray gun has the following advantages with usually using compared with desulphurization spray gun:
1, desulphurization spray gun forms by refractory castable is integrated poured usually, although in formulating of recipe, some designs are all adopted to offset the coefficient of expansion mismatch problem brought in rapid heat cycle process between metal and refractory materials, but this disadvantage that to be desulphurization spray gun be difficult to all the time overcomes, more or less there is stress relief and the crackle produced, serious restriction functional quality, efficient solution of the present invention rupture line produces, the problem of expansion, and the energy of stress rupture by bringing in spring pressure institutional solution rejected heat shake process.
2, desulphurization spray gun adopts vertical integrated poured usually, due to spray gun longer dimension, not only even vibrating head and vibrating motor ancillary vibration are all difficult to control the quality of making, entirety is split as several prefabricated components by the present invention, is conducive to making but also being easy to Mass Control.
3, because the present invention breaks through in traditional sense integrated poured, and be divided into several prefabricated components composition, so prefabricated component can adopt unlike material according to use position difference, and nonessential parts can be reused, and reach the object of energy-conserving and environment-protective.
4, integrated poured desulphurization spray gun is removed with pneumatic pick after using, not only take muscle power but also affect environment, the present invention can open spring pressure mechanism, makes convenient disassembly quick, reduces the labour intensity of workman.
